/'s ArroRNEx/s To all UNITED ',sLTATEs PATE-Nr v"onrein ETHAN I. nonns', or CENTRAL VALLEY, New Yoan 'who'm 'it may concern? l 4Be it knownI that I, ETHAN I. Donns, a

.citizenof the United States, residing in Central Valley, in-the county of lOrange and State of New York, have invented a new and useful Improvement in Railway-Car Trucks, of which the following is a specification.

My ,invention relates to improvementsin trucks for railway cars, and more particularly to improvements in metal car trucks The object of my invention is to vprovide an all steelsix wheeled passenger car truck, which 4will have a certain and proper amount of elasticity, and in which also the' truck center plate will be materially lower than in the constructions heretofore in use, thus enabling-the' car body itself to'have strong and deep centersills withoutfiucreasing the hei ht of thecar'body.

' y invention consists 'in the means employed to practically accomplish thisA object for result as 'herein shown and described and' more particularly specified in the claims.-

In the accompanying drawing forming a part of this specification, Figure 1 is a i' .plan view cfa six Wheeled passengercar truck embodying my invention. Fig. 2 is f a side elevation. Fig. 3 is a longitudinal secsection .o

tion on line 3-3 of Fig. 1. Fig. 4 isa cross n the broken line 4--4 of Fig.. 1. Fig. .5 is adetail perspective view of the' truck 4bolster and center plate. 6 is a detail perspective view of one of the foilged steel members 'of the truck bolster Fig. A 7 represents a modiiication in which the bolster members shown in Figs. 5

. the side frame of and 6 are cast in one integral piece. In the drawing, l represents the wheels 4of a six wheeled truck, 2 the axles, 3 the springs, 4 the equalizer bars, 5 the elliptic 6 the journal boxes and 7 the brake springs, y Y all of which maybe of any ordiapparatus,

nary or customary construction.

compression members 8 of The uppei or the truck consist of a pair l of rolled steel channels 9 placed with their webs back to back. The two compression me bers 8 `are tied together by means of transoms 10 which are `secured to the channels 9 by means of connecting castings 11 of cast steel, whichare provided with lugs v12 for the suspension. of the spring plank 13 Specication of Letters Patent.

through the medium of forged hangers 14. The side frame compression members 8 coinposed of the channels 9 are further tied together by compressed orrolled steel transoms 15, 16, through the connecting safet guards 27. The truck bolster lT, 18 is pre erably composed of .a c ast steel member 17 and a pair of forged steel bars'18 securely riveted to the` feet 19 of the cast steel meinber 17.

. The pedestals- 2Ol are of cast steel and extend between the upper or compression members 8 and the lower or tensionv members 21 of the truck'side frame. The tension members 21 preferably consisty of a rolledV channel 22 anda rolled rectangular iron member` 23 which are connected together by ing a transversely extending depressed cen-` ter plate member 30 connecting its longitudinally extending arched or truss shaped limbs v31', the feet 19 of which rest upon the transversely extending forged steel bolster members 18. The longitudinal members 31 of the bolster casting 17 are sufficiently spaced apart by the depressed center plate member 30 to give .room for the center sills of the car bdy between them so that the truck center plate 32 of the upper face of the depressed center plate member 30 is thus bolster member 17 is pref-4 brought very materially lower than the upper portion 33 of the truck bolster itself. This construction of truck bolster withl the center plate and center plate member 30 'extending'between and projectingbelow 'the lower face of the longitudinal members 31 which are spaced apart suiiciently to 4accommodate the center sills of the car body, and

'which at their trussed or arched portions project above the center plate member,I thus serves to bring the truck center plate itself comparatively low, so that wide and deep center sills may be enlployed'on the car body without raising its'height.v

.steel bolster having a depressed transi'ersely' I prefer to make the transverse bolster members 18, 18, of forged steel and in separate pieces from the cast steel .member 17 lof the bolster, as illustrated in Figs. 1 to 6 of the. drawing, butfif' desired, the bolster members 1S ma)v be cast integral with the .bolster member 1T, as illustrated in Fie. 7

of the drawing.

By combining together in the truck frame rolled or pressed steel compression members 8, pressed or .rolled steel tension member 2l tied together by pressed or rolled steel transoiiis l0, l5 and 1U in connection with the :ast steel pedestals Q0 and cast steel connecting castings .l1 and cast steel bolster 1T, I produce an all steel six wheeled car truck of great strength, and which at. the saine -time possesses the requisite amount ot elasA ticitb-v to render it easy in operation and cause it to be sate and reliable and exti'einel durable.
